Permanent gases such as CO, CO2, O2, N2, and methane are common analytes in refinery gases, natural gas, fuel cell gases, and many other industrial processes. Understanding the concentration of these components can be very important for controlling manufacturing processes, and impact the quality and commercial value of end products. Impurities such as CO and CO2 in feedstocks can be deleterious to certain catalysts resulting in disruption and increased cost of production. Agilent provides a family of factory tested - ready to use GC analyzers for analysis of permanent gases. Select from standard or custom analyzer configurations to find a system to address your specific analytical requirements.
